Abstract

An experimentally verified theoretical basis has been presented of the methodology of a materials’ fracture morphology description using a multifractal analysis of a stereometrically examined surface (full 3D analysis). High effectiveness of a multifractal analysis has been shown for a diversified multifractal spectrum width and for a quantitative description of overlaps. The values obtained are very similar to those obtained by the quasi 3D method [1] as well as by a conventional analysis which is an analysis of profile images obtained from transverse microsections.
The presented method, however, is the least time-consuming, the cheapest and seems to be the most objective in the scope of fracture morphology analyses.
